Namespace: OpenEdge.Web
Type: Class CompatibilityHandler
Parent Classes:
Progress.Lang.Object
OpenEdge.Web.CompatibilityHandler

Inherits: Progress.Lang.Object
Implements: Progress.Web.IWebHandler, OpenEdge.Logging.ISupportLogging

Copyright (c) 2015, 2018, 2021 by Progress Software Corporation. All rights reserved.
Purpose:Provide dispatching for WebSpeed for the PAS Web transport
Usage:Define as defaultHandler in openedge.properties for the WEB transport
Description:Manages startup of web/objects/web-handler.p and passes requests
to its process-web-request. The web-handler.p is a PAS variation
of the classic web-disp procedure.
This allows classic webSpeed applications and tools to run in a
PAS web application.
Author(s):hdaniels
Created:March 27 2015
Notes:Intended for migration of existing WebSpeed applications.
It is generally recommended that new web development for PAS web
transport use an implementation of the IWebHandler class that manages
the requests using OpenEdge.NetLib as base classes.
- The launched default web-handler procedure and WebSpeed utilities
have no knowledge of this class and does not have any reference
to the OpenEdge.NetLib.pl
@since:11.6
